LOOM TEMPLE Filed Sept. 27, 1935 A TTORNE YS.

Patented Apr. 5, 1938 PATENT OFFICE LOOM TEMPLE Robert Stevenson, Providence, R. I., assignor to Mechanical Holding Corporation, a corporation of Rhode Island Application September 6 Claims.

This invention relates to a loom temple for holding woven fabric taut in a widthwise direction in a loom, and has for one of its objects the provision of a loom temple which will be adapted for use with fabrics of varying thicknesses without manual adjustment.

Another object of the invention is the provision of a construction of loom temple which will operate upon fabrics of Varying thicknesses with substantially the same amount of frictional engagement regardless of the thickness of the cloth.

Another object of the invention is the elimination of markings on lightweight, fragile goods such as silk or rayon by the use of toothed rolls as occurs in the old style temple.

Another object of the invention is the provision of a loom temple the parts of which will need to be replaced less frequently than temples which have heretofore been in commercial use.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 8 is a sectional view on line 8-8 of Figure 7.

In the use of loom temples it is usually required that adjustments be made when varying thicknesses of fabrics are woven in the loom. In the Gilpin Patent No. 1,934,495, dated Nov. '7, 1933, with which I am familiar, an attempt has been made to provide an easy adjustment of a bar in the temple, but no adjustment occurs automatically nor is there any adjustment of the fabric engaging guiding edges, so that different surface frictions occur depending upon the thickness of the cloth woven in the loom; and in order to provide a device in which there will be substantially the same sinuous path provided through the temple and one in which the adjustments need not be made mechanically. I have provided a carriage for mounting a roll above the spaced base rolls so that the entire carriage with the roll is movable up and down and spring pressed toward the base, the edge of the carriage 27, 1935, Serial No. 42,473

serving as the guides for the fabric to determine its path of travel over the base rolls; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, I0 designates the base of the loom temple which is provided With spaced bearings II and I2 at one end and I3 and I4 at the other end for rotatably mounting in spaced relation the axles of the rolls I5 and I6. This base is provided with a suitable arm I'I having a lip I9 with holes 20. A bracket I8 adjustably receives the arm I1 for supporting the same in position on the loo-m. One end of the base is provided with a groove 22 which receives the tongue 23 of the cap and guide member 24 which has overhanging arms 25 of generally L-shaped cross-section with an elongated o opening 25 between them and, as shown in Fig. 5, is of generally rectangular form with a bridge piece 2'! connecting the arms 25 at their outer ends, said arms and bridge piece overhanging the base and being spaced therefrom.

A carriage 30 is mounted for vertical movement in the opening or space 26 between the arms 25, this carriage being provided with guide surfaces 3| to engage the inner surfaces 32 of the arms 25 on either side thereof, and a guide surface 33 on the upstanding portion 34 toy engage the inner surface 35 of the bridge piece 21 at one end and a guide surface 36 at the other end to engage the inner surface 3l between the arms 25 at the other end. Thus, this carriage is guided and may move vertically between the inner edges 32 of the arms 25 and the inner surface 35 of the bar 27 and the inner surface 31 of the body portion of this cap. The lower portion of the carriage below the surfaces 3| broadens to provide abutment surfaces 38 located beneath the arms 25, while the edges of the lower surface of the carriage are provided with lips 39 which are rounded to provide guide surfaces for the cloth 40 in passing from between the rolls. Resilient means such as a leaf spring 4I are located beneath each of the arms 25 to engage the surfaces 38 of the carriage to tend to force it downwardly. A groove 42 is provided on the underside of this carriage in which there is mounted a roll 43 in bearings 44 at either end thereof to be moved with the carriage toward the rolls on the base.

In operation, the woven fabric passes over the spaced rolls I5 and I6 and beneath the edges 39 and the upper roll 43, as shown in Figure 7. 'Ihe thicker the fabric the more the carriage will be forced up against the tension of the springs 4I, while the fabric will maintain substantially the same sinuous path and the same extent of frictional contact with the rolls regardless of its thickness. Further, by reasonof this loom temple no mechanical adjustments such as shimming up the cap or attempting to adjust screws or bolts or the like is necessary each time a different thickness fabric is operated on by the loom.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
